About the project

Microsoft Fabric Skills is a collection of reusable instructions and MCP systems that help AI assistants work with Microsoft Fabric workloads, APIs, queries, and operations. It is intended for users of GitHub Copilot CLI and compatible coding tools; the catalogue entries are the skills, agents, instructions, MCP systems, plugins, and rules distributed by the project.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

ModelPer sessionOnce invoked
Fable 5.1 $0.00091 $0.05324
Opus 5.5 $0.00036 $0.02130
Sonnet 5.5 $0.00018 $0.01065
Haiku 4.5 $0.00009 $0.00532

Security

Grade A, and why

onelake-catalog-cli scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 251 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Telemetry — MANDATORY. Every api.fabric.microsoft.com call must carry x-ms-fabric-skill: onelake-catalog-cli (az rest: --headers "x-ms-fabric-skill=onelake-catalog-cli"), including every LRO poll, fabric_lro and retry. Snippets omit it — add it anyway.

CRITICAL NOTES

  1. To find the workspace ID from its name, one call: az rest --method get --resource "https://api.fabric.microsoft.com" --url "https://api.fabric.microsoft.com/v1/workspaces" --query "value[?displayName=='<name>'] | [0].id" -o tsv (follow continuationToken only if it isn't on the first page; details in COMMON-CLI.md § Finding Workspaces and Items in Fabric).
  2. To find an item's ID, one call: the same on .../v1/workspaces/{ws}/items?type=<Type> with --query "value[?displayName=='<name>'] | [0].id".
  3. Write-gated skill — never call a write API before its gate below has passed. For curation that means the owner reviewed every proposed change and explicitly confirmed — not even a "test" write to check whether a change is allowed or what is already applied.
  4. The item list and Get Item both return an item's tags. An item with no tags has no tags field — that absence means untagged.

OneLake Catalog — CLI Skill (mode dispatcher)

One skill for the OneLake catalog. Govern (catalog health, protection and trust: audits and guarded remediation, by permission tier) and curate (an owner improving specific items' discoverability metadata) are modes, each detailed in a reference loaded on demand. This file picks the mode, holds every write gate, and indexes the references.

Mode selection

Mode Use when Load Writes
curate An owner wants specific items easier to find: a description, a clearer display name, tags, or table and column descriptions (items with a OneLake Tables folder) — one item, an explicit list, or one named workspace's weakly-described items references/curate.md ✅ after the owner approves each suggestion
dataowner-audit A non-admin workspace or domain owner wants governance posture for workspaces they administer (widen to accessible on request; Core API) references/dataowner-audit.md ❌
dataowner-remediate A data owner who is also a domain / workspace / capacity admin fixes a governance finding — single-workspace domain or capacity assignment, workspace tags, refresh, item identity (Core & Power BI APIs, no tenant admin), including dry runs of these references/dataowner-remediate.md ✅ self-service
admin-audit A Fabric tenant admin wants tenant-wide governance posture (/v1/admin/*) references/admin-audit.md; any tenant count starts from admin-audit-scope.md ❌
admin-remediate A Fabric tenant admin makes tenant-wide writes — domains, bulk assignment, domain roles, bulk labels, tenant tag definitions, tenant settings references/admin-remediate.md ✅

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
